Renewed March 16, 1932 siclaims; (01. 105-234) Ourinvention relates to locomotive tenders in which stoker mechanism is used and has for one of its main objects the provision of a tender constructed to permit mounting the. stoker drive mechanism comprising either gearing, the stoker engine, or both in a compartment adjacent or back of the rearward end of the stoker fuel the line lu-la of Fig. 1;

Fig. 1;

trough. The invention further contemplates forming a tender and its stoking mechanism so that the conveyor screw may be withdrawn and replaced from the rearward end of the tender without the necessity, as'exists in present practice, of uncoupling the locomotive and tender.

Other objects such as providing a stoker, gear casing removably mounted in a water tight compertinent at the rear of the stoker trough to form a closure between the open rearward end -of the trough or the fuel bin and the aforesaid Fig. 2 is a plan section on the line 2-2 of Fig. 3 is asection on. the line 3,3 of Fig. 1;

1 Fig. 4 is acentral vertical longitudinal section of a. modified' form of the mechanism of Fig. 1; and

Fig. 5 is a plan section on the 1ine'-5-5 of Fig. 4.

tender and stoker The locomotive tender is indicated generally at In and a portion of the-locomotiveat ill The tender body portion is formed with the fuel compartment l2 and the water compartment l3 separated fromeach other by the rear slope sheet I; the side slope sheets Ila, fastened at their lower marginal portions, as best shown in Figs. 1,

and 1a, to atro'ugh member iii to form a water tight partition wall. The trough 15 at its forward end is joined to suitable plates to form a forward closure for the water section,

The tender base or frame is shown at l6' and comprises the side sills. lta, the center sills 16b, the bottom web or base plate l1 and a top web or upper plate I! connected by the transverse transoms or ribs l9, and extends from one end of the tender to the other. The base plate I1 is solid, but the upper plate It has a series of per-' forations 20, and the ribs are apertured at 2|, so that water from the water compartment can circulate freely in the space between the two plates I1 and. Ill. The trough member Ibis shown in they drawings as an integral part of the frame I6 disposed within the water section, but it will be obvious that it may be formed as a separate member supported from the frame by suitable foot members.

,The floor 22 of the fuel compartment i2 is provided with a central longitudinal opening 23 communicating with the' trough l5 and through which fuel is supplied to the trough by gravity. Plates 25 are slidably mounted in the opening 23, and may be moved from covering position to permit entry of the fuel into the trough as the supply becomes depleted.

The trough l5 communicates with a bowl 2!; through an opening 21 in its forward end. The

bowl 26 is received in a spherical portion of thevertically split coupling member. 28 carried by I the tubular section 28 which leads forwardly to deliver fuel to the locomotive firebox in any suitable manner.

Suitable mechanism is employed for crushing and for copveying =fuel, including a screw 30 mounted in the trough l5 and extending longitudinally forward intothe bowl 26 and a crushing abutment 3| at the forward end of the trough and arched over the screw 30 for engaging the fuel to crush it to a proper size for firing.

Referring now more particularly to Figures 1,

2 and 3, the trough l5 opens rearwardly into av 35, the top wall 36 and the side wall 31. The

upper plate ll of the tender frame It forms the bottom wall of the compartment 32 and the re-' movable cover 38 in the tender sidewall 33 'forms the other sidewall thereof. The rear wall 33 of the compartment 32 s provided with an opening 39 communicating with a sleeve whichex tends longitudinally of the tender along the extended axis of the screw 30 opening rearwardly in the upri ht rear wall ll of the tender. A detachable cover 42 forms a closuie for the rearward opening of the sleeve .40. The plates constituting the walls forming the compartment 32- may be secured in any suitable manner to a framework consisting ofthe upright angle bars 32a and the horizontal angle bars 32b.

The compartment 32 houses the stoker driving mechanism making it easily and conveniently accessible for purposes of inspection, repair and replacement through the opening in the side of the tender by removing the cover 38. The driving mechanism comprises a motor 43 mounted in the compartment 32 at one side of the openings to the trough l5 and the sleeve 40 and a gear casing 44 removably mounted in the compartment 32 normally forming a closure for the opening to the trough I5. The motor 43 operates the drive shaft 45 which, transmits motion to the shaft 45 coupled to the drive shaft 45 by the coupling member 41. The gear 48 carried by the shaft 46 engages the gear 49 mounted on the shaft 50 transmitting motion thereto, which inturn operates the screw 30. This arrangement permits withdrawal of the screw an through the com partment 32 and the sleeve40 without necessitating' uncoupling of the locomotive and tender. It may be done conveniently by removing the bolts 5|, removing the coupling 41, drawing the shaft 45 apart from the shaft 46 permitting sufficient clearance for withdrawing the gear casing 44. f

Figures 4 and 5 illustrate a modified arrangement in which a motor and gear housing compartment 52 extending transversely of the tender is located at the rear thereof. This compartment 52 forms a recess in the water compartment at one of the rear corners, enabling the drive mechanism to be mounted outside or exteriorly of the water compartment and shielding the drive mechanism fromthe water therein. The opening through which access to the interior of the comartment 52 is gainedis in the rear upright wall of the tender and is closed by the removable cover 53. A longitudinally extending sleeve 54 communicates at its forward end with an opening in the rearward end of the trough l5 and at its rearward end with an opening in the front wall of the compartment 52. A screw conveyor 55 is mounted in the trough l5 and extends rearwardly into the sleeve 54 for a few turns. The flights of the screw 55 in the sleeve 54 have a larger diameter than the remaining flights and slightly less than the diameter of the sleeve to fit snugly therein. When clogging or jamming occurs it is usual to reverse the screw 55 for about a half a turn to relieve it, and some fuel will be carried into the sleeve 54. L This fuelwill be swept back into the trough by the enlarged flights in the sleeve when the screw is again rotated to advance fuel. The shaft 55 of the screw conveyor 55 extends rearwardly into the compartment 52 and is supported by the bearing 51 which forms a closure for the opening between the sleeve 54 and the compartment 52.

The screw conveyor 55 is operated by a motor 58 through gearing 59, in the same manner in which the screw 30 in the preferred form is driven. The screw 55 may readily and conveniently be withdrawn through the rear of the tender by removing the cover 53, removing the coupling member 60, detaching the gear housing from the floor of the compartment 52 and withdrawing the screw 55 rearwardly through the sleeve 54 and the compartment 52.
